We synthesized diblock copolymers of poly(butyl methacrylate)-b-poly(N-isopropylacrylamide) (PBMA-b-PIPAAm) with various thermoresponsive PIPAAm chain length. Polymers were dissolved in mixed solvent of acetonitrile/N, N-dimethylformamide (5/1 in v/v), and the solution was deposited on the surface of commercial cell culture substrates using a spin coater. Chemically connected hydrophobic PBMA significantly enhanced physical absorption to target material surfaces and resulted in introducing thermoresponsive property to solid surfaces. To investigate temperature-dependent cellular behavior, bovine carotid artery endothelial cells were seeded on polymer-coated surfaces and cultured at 37 °C. Cells adhered and proliferated on temperature-responsive surface at 37 °C, while the efficiency of adhesion and proliferation became lower with increasing PIPAAm chain length. On the other hand, longer PIPAAm chains significantly promoted cell detachment from the surfaces by reducing temperature to 20 °C. Consequently, confluently cultured cells were successfully harvested as a single cell monolayer with maintaining cell-cell junctions and extracellular matrix proteins with simple low temperature treatment by choosing the adequate PIPAAm chain length of block copolymer.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126049035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High force accuracy is an important factor to grasp an object stably and not to damage the grasping object. In the previous research, our exoskeleton achieved high pinching force accuracy at the same level of human ability and extended range of the human pinching force to about twice by 46% reduction of affecting force to the finger part from the exoskeleton. However, 46% load reduction of the exoskeleton is not enough to exert more than twice human pinching force which is required by some workers because a user's sensitivity to recognize change of the force is getting worse by fingertip deformation. For extension of the pinching force range maintaining high force accuracy, the characteristics of fingertip sensitivity is considered so that the wearer could estimate the support force precisely. Then we developed a new exoskeleton which reduces affecting force to 67%. Through experiments, our exoskeleton can augment a user's force by about triple, maintaining its force accuracy at the same level of human ability.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124356962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
